When Xiaomi’s smartphone refuses to start because of a faulty or sliding power button, it can take anyone by surprise.This is not just an inconvenience, but a real problem if the device is completely dead or requires a forced restart of the getting stuck system. Owners of budget and flagship models Redmi and Poco often face mechanical wear of the key contacts, making the usual way of activation impossible.
But the modern architecture of Android and the MIUI shell offer several workarounds to launch the device: you don't have to bring it to the service center or look for a soldering iron right away. There are a number of software and hardware methods that allow you to activate the screen and start the operating system even with a completely non-functioning physical switch.
In this article, we'll go into all the ways you can do this, from simple charger manipulation to complex computer commands, and it's critical to understand that some methods require you to pre-tuning your USB debugging, which must be active before you turn off your phone, and if you haven't prepared in advance, the choices are narrowed, but they still exist.
Use of Volume button and Recovery Mode
The most common method that works on most Xiaomi, Redmi and Poco devices is to use a volume key combination, which allows you to log into a special Recovery menu, where you can initiate a system reboot, which is effective if the phone's battery is not completely drained, but the device is turned off.
First, connect your smartphone to the charger or computer through USB-Press the Volume Up button and hold it. At that point, plug the power cable. The screen should light up, and you'll see the Mi logo or the Recovery Mode menu with a few points.
Navigation on this menu is done with volume buttons and optional choice with the power button. Because the power button doesn't work, this may seem like a dead end, but on many versions of MIUI, there is a hidden feature or timeout that allows you to select "Reboot" simply by holding the volume button for a long time or waiting for an automatic selection.
⚠️ Note: If you see "Wipe Data" in the Recovery menu, do not select it if you want to save personal files.
If the automatic choice doesn't work, try the "blind" reboot method. Press the volume button, plug the cable, wait for the menu to appear, count 5-7 seconds (usually the first item), and press the volume button again, simulating the choice. Also, it sometimes helps to quickly press the volume button immediately after the logo appears.
☑️ Actions in Recovery Mode
Starting through a computer connection and ADB
If your device has pre-enabled debugging USB (USB Debugging, you have a powerful tool to control the system, and the computer can send a command to turn on or restart without having to push physical buttons. ADB cable.
Connect the phone to your computer when it's off. In some cases, connecting to the USB 3.0 port (blue) can trigger a device to wake up if the battery isn't deep. If the screen catches fire but the system isn't loading, open the command line on your PC in the ADB tool folder.
Type a command to check the connection: adb devices. If the device is displayed in the list, then the connection is established. To try to turn on, use the adb reboot command, which will send a signal to restart. If the phone was simply turned off programmatically, it can start.
adb rebootIf the standard reboot doesn’t work, you can try the command to enter the recovery mode: adb reboot recovery. This often helps to “brake off” the hung power controller. The success of this method depends on whether the battery is still charged and debugging is not disabled after switching off (on some models it is reset).
Why can't ADB work?
The discharged battery method and automatic start
One of the simplest, though time-consuming, ways to do this is to use Xiaomi’s power controller at a critical charge level: If you completely drain your smartphone battery to 0% and then put it on charge, the device can turn on automatically.
The idea is that many modern power controllers are programmed to start automatically when a certain voltage threshold is reached, enough to keep the phone charging for a few hours, preferably using the original charger and cable.
It's important not to touch the device while charging. Sometimes the phone may flash the light several times or show the battery logo, then go out and turn on again. This cycle may repeat. If after 3-4 hours of charging the phone does not turn on itself, try to press the volume button while it is on charging.
- 🔋 Use a powerful charger (minimum) 10-18 W) for rapid battery pumping.
- ⏳ Leave your phone charged overnight or at least 4-5 idle.
- 🌡️ Watch the temperature of the case; if the phone is very warm, interrupt the charging.
This method is particularly effective for models with non-removable batteries, where the controller has priority charging over the state of off.If after a long charge when connecting the cable the screen lights up, but the system is still in place, try quickly pressing several times on the screen or using the method with a volume clamping.
Use of third-party applications and accessories
If the phone is able to turn on one of the above methods, but the power button stopped working permanently, urgent measures must be taken to further use. There are applications that allow you to emulate the power button programmatically or through sensors.
One popular solution is to use apps like Gravity Screen or Button Mapper, which allow you to set the screen on when you lift your phone, tap the case or connect the charger. For full-on from scratch (from the off state), the software is powerless, but for waking up from sleep is ideal.
It is also worth considering the purchase of an accessory in the form of USB-mouse or keyboard with support OTG. By connecting your mouse to your phone (if it’s on or on through charging), you can control the interface. Some Xiaomi models allow you to set up the screen to turn on with a double mouse click.
⚠️ Note: App installation is only possible if the phone is already on. Use this section as a preventive measure or if you have been able to temporarily start the device.
Another option is to use a smartwatch or Mi Band bracelet, which when paired with a phone can perform the function of a remote control, including a notification screen or running apps, which partially compensates for the lack of a physical button.
Hardware methods and closing of contacts
For advanced users who are not afraid to disassemble a smartphone, there is a method of directly closing the contacts of the power button on the motherboard, which requires accuracy, thin tools and an understanding of the electronics device.
You take off the back cover (or the display module if you have a unibody design) and find the plume that goes to the power button. On the board itself, there are two contacts under the button, and if you lock them with tweezers or a needle, you simulate the push of a button.
Often on Xiaomi boards, the power button contacts are available even without a full charge if you bend the protective screen. Be careful: shorting the wrong contacts can permanently disable the device.
| Method | Difficulty | Risk of damage | Essential tools |
|---|---|---|---|
| Charging the battery | Low. | Minimum | Charger |
| Recovery Mode | Medium | Low. | Volume buttons |
| ADB Teams | Tall. | Medium. | PC, cable, drivers |
| Close of contacts | Expert | High-pitched | Tweezers, screwdrivers. |
If you decide to disassemble, make sure that the battery is disconnected from the plume before any manipulations inside the case. After closing the contacts and the appearance of a vibration or logo, immediately connect the power cable so that the phone does not go into a reboot cycle.
💡
If you've disassembled your phone, order a new power button on AliExpress or at your local parts store. Temporary circuiting is a 5-minute solution, not a permanent one.
Prevention and setting up of the inclusion schedule
To avoid a situation where the phone is turned off and cannot be turned on, use the On/Off Planner function. This option built into MIUI allows you to set up the automatic start of the device at a certain time.
Go to settings, look for Battery or Advanced Settings (the path may vary depending on the Android version), find Scheduled Tasks and turn on the Power-on option. Set a time for example 8:00 a.m.
Now, even if your phone runs out and turns off, when you connect to the network (or just by a timer if the charge is left), it will try to turn on at a given time.
- ⏰ Set daily on for the time you normally wake up.
- 🔋 Make sure the charge level does not fall below. 10-15% sleep-time.
- 📱 Use Safe Mode to check if a third-party application blocks the button’s operation.
It's also recommended that you turn off the Quick Start feature in the battery settings. Although it speeds up the turn on, it puts the phone into a deep hibernation, which is harder to exit without a power button than from a full shutdown.
💡
The most reliable way to avoid problems with the inclusion is to prevent the full discharge of the battery and set up automatic switching on schedule in the system settings.
